I guess here's my question- why is it necessary to change a barrel out so fast? If it's just something you want to buy for the heck of it, have at it. Nothing wrong with that. If your concern for it is because you can't pop two pins fast enough, what is going on that you need to get the rifle apart or together so fast?
The problem more than anything is that you are severely limiting your options for barrel and receiver selection, and given how limited of a market it is out there for the barrel change option you want, you are really not going to have any proven platforms available to you. When this gimmicky stuff comes out- because that's what it is- you have to consider why you don't see major companies doing it like BCM, DD, HK, FN, etc. Quality quick-change barrel systems exist like what is offered by LMT, but that is a different concept that is not meant for quick toolless field-expedient disassembly and assembly for storage.
Using military rifles as an example of problems is misleading. Most military rifles are heavily abused and regularly get damaged by training, use and insanely excessive over-cleaning that destroys tolerances. If you have pins sticking, that's a tolerance stacking issue. If you buy a rifle commercially, you can weed out this problem by getting a rifle with an appropriately matched receiver set.
